SUS301 (301L)
301 (301L) Austenitic Stainless Steel
Introduction & Properties
Austenitic stainless steel SUS301 (301L) has lower amount of Ni, Cr and higher amount of N than that of SUS304,and can achieve high strength through processing . Although no magnetic first, magnetic exists after cold rolling. And SUS301 (301L) has excellent strength under high temperature as well as fatigue strength and corrosion resistance, and one of its advantages is to reduce weight with excellent safety and economic advantage.
